5 Claims, 6 Drawing Figures 1 DEFLECTOR PLATE SUPPORT This invention relates to supporting means for a deflector plate forming a part of a spray nozzle.

More specifically the nozzle may be of the 360 type as disclosed in co-pending application Ser. No. 173,174, filed Aug. 19, 1971, wherein a nozzle element directs a jet of liquid axially onto a deflector plate adapted to deflect the liquid radially around its entire periphery.

An object is to provide novel and improved means for mounting and adjusting the position of such a deflector plate.

Another object is to provide a mounting in which the deflector plate may be adjusted axially and transversely.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

In one embodiment the deflector plate is mounted on a rod which extends through a ball joint carried in the wall of an air duct leading tothe spray zone. The ball is mounted for angular adjustment in the duct wall and the rod is slidably mounted in the ball for axial adjust ment. In another embodiment the rod extends through a resilient bushing which permits pivotal adjustment of the rod. In both cases a universal adjustment is obtained.

The specific nature of the invention will be better understood from the following description, taken in connection with the accompanying drawing in which a specific embodiment has been set forth for purposes of illustration.

In the drawing:

FIG. 1 is a vertical section through a mounting means embodying the invention;

FIG. 2 is an enlarged detail section taken on the line 2-2 of FIG. 1 showing the mounting for the ball;

FIG. 3 is a section similar to FIG. 2 illustrating a further embodiment of the invention;

FIG. 4 is a section similar to FIG. 1 showing a still further embodiment; and

FIGS. 5 and 6 are detail sections taken on the lines 5-5 and 6-6 respectively of FIG. 4.

Referring to the drawing more in detail the spray element is shown as embodied in a washing module 10 consisting of a cylindrical element having a restricted zone 11 forming a venturi effect for the air or gases passing therethrough either upwardly or downwardly. The module 10 is provided with a top flange 12 to which is connected the flange 13 of a duct 14 having an elbow forming a transverse wall 15 for supplying thereto air'or gases to be washed.

A nozzle element 16 is fixed in the module 10 to direct a jet of liquid upwardly at the axis of the module and a deflector plate 17 is disposed in axial alignment with the nozzle element 16 for deflecting the liquid radially outwardly around its entire periphery in the form of a uniform 360 spray. Washing apparatus of this type is shown more in detail in the co-pending application above mentioned and only so much thereof is set forth herein as is necessary for an understanding of this invention.

In FIGS. 1 and 2 the deflector plate 17 is shown as mounted on a rod 18 which extends axially through a ball element 19 and is clamped therein by a clamping ring 20 and a threaded retaining ring 21. This retaining ringpermits the rod 18 and deflector plate 17 to be adjusted axially of the module as required.

The ball 19 rests on an internal flange 22 of a cylindrical sleeve 23 which is secured in the transverse wall 15 of the duct 14. The ball 19 is clamped in adjusted position by retaining rings 24 and by a cover plate 25 which is clamped by bolts 26 engaging a flange 27 on the sleeve 23.

The arrangement is such that radial adjustment of the deflector plate 17 may be made by loosening the cover plate bolts 26 and adjusting the position of the free end 28 of the rod 18 so as to pivot the rod about the center of the ball as a pivot point. The assembly can then be clamped in position as desired. The deflector plate 17 can thus be adjusted to provide the desired spray pattern.

The embodiment of FIG. 3 is generally similar to that above described and corresponding parts have been given the same reference numbers with the suffix a. In this form the ball 19a is provided with an extended hub portion 30 having set screws 31 by which the rod 18a is clamped in position in the ball. The cover plate 250 is formed with an annular flange 32 extending into the bore of the sleeve 23a to clamp the retaining ring 24a in place.

In the embodiment of FIGS. 4 to 6 the support rod 18b and adjusting means are disposed within the confines of the module 10b. The rod 18b extends through a resilient bushing 40 held in a sleeve 41 mounted in a spider having radial legs 42 and an outer ring 43. The ring 43 is clamped between flanges 12b and 13b of the module 10b and duct 14b respectively. The sleeve 41 carries a series of set screws 44 which engage and secure the rod 18b in place.

In this embodiment the rod 18b may be adjusted axially by loosening the set screws 44 and may be adjusted radially by suitable manipulation of the same set screws. The bushing 40 is sufficiently resilient to permit the rod 18b to pivot therein to accommodate the desired radial adjustment.

While certain specific embodiments have been set forth for purposes of illustration it is obvious that various changes may be made therein within the scope of the appended claims.
